How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC may
also modify the rate of inflation based on the occupant
size provided by the Occupant Classification Module.
The ORC will not detect roll over.
•The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.
•Also, the ORC turns on the airbag warning
light and PAD indicator light in the instru-
ment panel for 6 to 8 seconds for a self-check
when the ignition is first turned on. After the
self-check, the airbag warning light will turn off. The
42 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
The PAD indicator light should not be illuminated
when teenagers, most children in a forward-facing
child restraint or booster seats, most children that can
properly wear the vehicle’s seat belt, and when an
adult passenger is properly seated in the front passen-
ger seat. In this case, the air bag is ready to be inflated
if a collision requiring an air bag occurs.
For almost all properly installed rear facing child
restraints, the PAD indicator light will be illuminated
indicating that the front passenger air bag is turned off
and will not inflate. If the PAD indicator light is not
illuminated,DO NOTassume the air bag is turned off
and move the child restraint to the rear seat. A
deploying passenger air bag can cause death or seri-
ous injury to a child in a rear facing infant seat.
NOTE:NOTE: Even though this vehicle is equipped
with an occupant classification system, children 12 years
and under should always ride buckled up in a rear seat in
an appropriate child restraint (see section on child re-
straints).

* Since the system senses weight, some small objects
will turn the PAD Indicator Light on.
The OCS classifies an occupant using weight sensors
mounted in the base of the front passenger seat. Any
weight on the seat will be sensed by the system. Objects
hanging on the seat or other passengers pushing down
on the seat will also be sensed. The weight of an adult
will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
properly classified. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the PAD
Indicator Light is not illuminated when an adult is riding
in the front passenger seat. If an adult occupant’s weight
is transferred to another part of the vehicle (like the door
or instrument panel), the weight sensors in the seat may
not properly classify the occupant. Objects lodged under
the seat or between the seat and the center console can
prevent the occupant’s weight from being measured
properly and may result in the occupant being improp-
erly classified. Ensure that the front passenger seat back
does not touch anything placed on the back seat because
this can also affect occupant classification. Also, if you
fold down the rear seat check to be sure it doesn’t touch
the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.If there is a fault present in the OCS, the Airbag Warning
Light (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The Airbag Warning Light is turned on
whenever there is fault that can affect the operation of the
airbag system. If there is a fault present in the OCS, both
the PAD Indicator Light and the Airbag Warning Light
are illuminated to show that the passenger airbag is
turned off until the fault is cleared. If an object is lodged
under the seat and interferes with operation of the weight
sensors, a fault will occur which turns on both the PAD
Indicator Light and the Airbag Warning Light. Once the
lodged object is removed, the fault will be automatically
cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the

upper right side of the instrument panel separate and
fold out of the way as the bags inflate to their full size.
The bags fully inflate in about 50 - 70 milliseconds.
This is about half of the time it takes to blink your eyes.
The bags then quickly deflate while helping to restrain
the driver and front passenger. The driver’s front
airbag gas is vented through vent holes in the sides of
the airbag. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
troller (ORC). The ORC uses the occupant category to
determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
•Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•TheSide Impact SRS Side Curtain Airbagare de-
signed to activate only in certain side collisions. When
the ORC (with side impact option) detects a collision
requiring the side curtain airbag to inflate, it signals
the inflators on the crash side of the vehicle. A quantity
of nontoxic gas is generated to inflate the side curtain
airbag. The inflating side curtain airbag pushes the
outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30
milliseconds (about one quarter of the time it takes to
blink your eyes) with enough force to injure you if you
are not belted and seated properly, or if items are
positioned in the area where the side curtain airbag
inflates. This especially applies to children. The side
curtain airbag is only about 3-1/2 inches (9 cm) thick
when it is inflated.
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
The ESP enhances directional control and reduces driving
wheel spin of the vehicle under various driving condi-
tions. The system operates when the vehicle speed is
greater than 7.8 mph (12.6 km/h).
The ESP system corrects for over/understeering of the
vehicle by applying brakes to the appropriate wheel.
Engine torque is also limited.
The ESP warning light, located in the instru-
ment cluster, starts to flash as soon as the ESP
system sensor’s information varies from the
driver’s intended path. The ESP warning light
also flashes when traction control is activated. If the ESP
warning light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the prevailing
road conditions. When the ESP warning light is illumi-
nated continuously, the ESP is switched off. To return to
the enhanced vehicle stability offered by ESP, press the
ESP switch (the ESP warning light in the instrument
cluster goes out). Avoid spinning one drive wheel. This
may cause serious damage to the drive train.To improve the vehicle’s traction when driving with
snow chains, or starting off in deep snow, sand or gravel,
switch off the ESP system by pressing the ESP switch.
With the ESP system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced
vehicle stability offered by ESP is unavailable. ESP al-
ways operates under braking, even with the switch in the
OFF position. When the ESP system is disabled (if one
drive wheel loses traction and begins to spin) the brake is
applied by the ESP system to control wheel slip. This

The operation of the Brake Warning Light can be checked
by turning the ignition switch from the OFF position to
the ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
21. Vehicle Theft Alarm (VTA) Indicator Light
The VTA indicator Light flashes rapidly when the VTA is
arming, and slowly when the VTA is armed. (See page 25
for more information.)
22. Tire Pressure Monitor Warning Light—If
Equipped
This light will turn on continuously when
there is a Low tire pressure condition. The
light will also turn on if a problem exist with
any tire sensor. When a system fault isdetected, the indicator light will flash repetitively for
ten seconds. The flash cycle will repeat every ten
minutes or until the fault condition is removed and
reset. The light will remain on or flashing until the tire
pressure is properly set or the problem with the sensor
is corrected.
This light will turn on momentarily as a bulb check when
the engine is started.
When the tire pressure monitoring system warning light
is lit, one or more of your tires is significantly underin-
flated. You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the Tire and Loading Information Placard.
Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
Each tire, including the spare, should be checked
monthly when cold and set to the recommended inflation
pressure as specified in the tire and loading information
placard.

Compass Variance
Compass Variance is the difference between magnetic
North and Geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. If this occurs, the compass variance must be set.
NOTE:Magnetic materials should be kept away from
the overhead console. This is where the compass sensor is
located.

Floor
Air flows through the floor outlets located under
the instrument panel and into the rear seating
area through vents under the front seats.
Bi-Level
Air flows both through the outlets located in the
instrument panel and those located on the floor.
Air flows through the registers in the back of the
center console to the rear seat passengers. These
registers can be closed to partially block airflow.
Panel
Air flows through the outlets located in the instru-
ment panel. Air flows through the registers in the
back of the center console to the rear seat passengers.
These registers can be closed to block airflow.
Recirculation
The recirculation feature can be selected with
the mode control knob. You may choose be-
tween Bi-Level Recirculation and Panel Recir-
culation air outlets while in this mode. Nor-
mally, air enters from outside the vehicle. However,
when in Recirculation mode air inside the vehicle isre-used. Use this mode to rapidly cool the inside of the
vehicle. The Recirculation mode can also be used to
temporarily block out outside odors, smoke, and dust.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Automatic Temperature Control—If Equipped
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by a dual
sun-sensor in the top of the instrument panel, and an
infrared sensor located in the face of the control unit.
There are also various sensors monitored by this system
which take account for vehicle speed, A/C pressure,
outside temperature, and engine cooling temperature.
